Abstract

The invention relates to phosphonodroxyacetonitrile and a process for its production which comprises reacting phosphono formaldehyde, in salt form, with hydrocyanic acid (then, if desired, converting the free phosphonohydroxyacetonitrile to salt thereof. The phosphonohydroxyacetonitrile is useful, for example, as an intermediate for the production of phosphonohydroxyacetic acid, an antiviral agent.

Das erfindungsgemäße Phosphonohydroxyacetonitril kannin Salze übergeführt werden.The phosphonohydroxyacetonitrile according to the invention canbe converted into salts.

Phosphonoformaldehyd ist noch nicht bekannt. Er kann hergestellt werden, indem man Dialkoxymethanphosphonsäuren ^BuIl. Chem. Soc. Japan 51. (1978), 21697 mitWasser erwärmtundgegebenenfallsmit einerBase umsetzt,Phosphonoformaldehyde is not yet known. It can be prepared by adding dialkoxymethanephosphonic acids ^ BuIl. Chem. Soc. Japan 51. (1978), 21697 heated withwater andoptionally reacted with abase,

AlsAusgangsstoffe für das erfindungsgemäße Verfahreneignen sich anorganische oder organische Salze des Phosphonoformaldehyds, beispielsweise anorganische SaI-ze,wie z.B. das Natriumsalz, aber auch organische Salze, wie z.B. das Triethylammoniumsalz.Suitable starting materials for the process according to the invention are inorganic or organic salts of phosphonoformaldehyde, for example inorganic salts such as the sodium salt, but also organic salts such as the triethylammonium salt.

Als Cyanwasserstoffsäure eignen sich wasserfreie Cyanwasserstoffsäureoder konzentrierte wäßrige Lösungen von Cyanwasserstoffsäure.Anhydrous hydrocyanic acid is suitable as the hydrocyanic acidor concentrated aqueous solutions of hydrocyanic acid.

Es ist zwar grundsätzlich möglich, auch Alkalisalze der Cyanwasserstoffsäure, beispielsweise Natriumcyanid,in Verbindung mit einer Bisulfitverbindung des Phosphonoformaldehydseinzusetzen. Dieses Verfahren ist aber weniger zweckmäßig, da die zusätzlich entstehendenanorganischen Salze, wie Natriumsulfit, durch zusätzliche Trennoperationen entfernt werden müssen.It is in principle possible to also use alkali metal salts of hydrocyanic acid, for example sodium cyanide,in connection with a bisulfite compound of phosphonoformaldehydeto use. However, this method is less expedient because the additional ones that ariseInorganic salts, such as sodium sulfite, have to be removed by additional separation operations.

Als Verdünnungsmittel für die erfindungsgemäße Reaktionkommt Wasser in Frage. Man kann aber auch bei Verwendung von in Cyanwasserstoffsäure löslichen SaI-zenohne zusätzliches Verdünnungsmittel arbeiten.As a diluent for the reaction according to the inventionwater is an option. But you can also use salts soluble in hydrocyanic acidwork without additional thinner.

Das erfindungsgeraäße Verfahren wird in einem Temperaturbereichvon 00C bis +400C, vorzugsweise zwischen+150C und +300C, durchgeführt.The erfindungsgeraäße process is in a temperature range of 00 C to +400 C, preferably between +150 C and +300 C is performed.

Im allgemeinen setzt man 1 Mol der Verbindung (II)mit 1 bis 20 Mol, vorzugsweise mit 1,2 bis 5 Mol Cyanwasserstoff säure, um. Ein größerer Überschuß an Cyanwasserstoff säure schadet nicht, wenn beispielsweisein wasserfreier Cyanwasserstoffsäure als Verdünnungsmittelgearbeitet wird.In general, 1 mol of the compound (II) is usedwith 1 to 20 moles, preferably with 1.2 to 5 moles of hydrocyanic acid, to. A larger excess of hydrocyanic acid does no harm if, for examplein anhydrous hydrocyanic acid as a diluentis being worked on.

Die Reaktionsdauer ist von der Temperatur abhängig und liegt zwischen 15 Minuten und 3 Stunden.The reaction time depends on the temperature and is between 15 minutes and 3 hours.

Die erhaltene Verbindung (I) kann durch Eindampfen der Lösung und gegebenenfalls sich anschließende Entsalzungan einem saueren Ionenaustauscher isoliert werden.The compound (I) obtained can be purified by evaporation of the solution and, if appropriate, subsequent desalinationbe isolated on an acidic ion exchanger.

Das Phosphonohydroxyacetonitril ist ein Zwischenproduktfür die Herstellung der antiviral wirksamen Phosphonohydroxyessigsäure.The phosphonohydroxyacetonitrile is an intermediate productfor the production of the antiviral active phosphonohydroxyacetic acid.

Beispielsweise kann das Phosphonohydroxyacetonitril durch Verseifen der Nitrilgruppe mit Salzsäure, indie Phosphonohydroxyessigsäure überführt werden.For example, the phosphonohydroxyacetonitrile by saponifying the nitrile group with hydrochloric acid, inthe phosphonohydroxyacetic acid are transferred.
